Bathroom fan switch

[joeturbo]

Afternoon all,

Hoping for some advise, I have just purchased a 12 year old appartment and am going through the stages of decorating.

One thing I would like to do is replace the extractor fan switch (located outside of the bathroom) with a new one. Reason being is its looking quite old and is a yellowing colour, just a bit of an eye sore.

The switch is connected to the lighting as it goes on/off with the light switch. Is this a easy job to do a straight swap with a newer clean white version?

Thanks

Is it a three pole isolator

or just a normal switch for operation.

Thanks for the quick reply, I will take a photo and post tomorrow (I work evenings)

I bet it dont have a fuse spur?

Even with a 3 pole switch you should still have a 3amp fuse in a fuse spur.

.... IF the manufacturer of the fan says so (at least for the next few months) - but do you really believe that, in practice, a 3A fuse affords significantly more protection than a 5A fuse or 6A MCB?

Kind Regards, John

I know, but say a fault arise on the fan, whould the 3amp blow 1st or the mcb trip?
And would you think its for the manufacturer to cover there back incase of a fire ect

More-or-less pot luck, I would say - but I would suspect that it would probably more often be the 6A MCB which operated first. Like many others, I've quite often seen a 32A MCB trip without a 13A fuse in a plug or FCU in the fault path blowing.

And would you think its for the manufacturer to cover there back incase of a fire ect

Fuses/MCBs in the installation should really only be there to protect the installation's fixed wiring. If the fan manufacturer feels that the innards of their fan require more protection than the installation's OPDs will provide, they should really provide internal protection within their product. ... but, anyway, again, the chances of a 3A fuse preventing a fire which a 5A MCB would not prevent are, IMO, minimal - as I said, it's quite possible that the MCB would trip before the fuse blew, anyway!

Kind Regards, John

I always think it's there to give the maker a way to weasel¹ out of any warranty claims.

Yes.

 

[joeturbo]

Would it be easy to replace? Diy job?

 

[AndyPRK]

Yes as long as your turn off the lighting circuit at the CU.

There will be at least 6 wires, so you carefully need to copy them over (taking photos is a good idea before starting)

Search for fan isolator switch on the internet.

many thanks, I have ordered 2 of the first link as they look like a identical straight swap.

Many thanks
